Kes, a world of rock and ice, existed as a planet found in the Tirahnn system. This system was situated within the Zeemacht Cluster sector, a segment of the Inner Rim. Circling the star known as Tirahnn, Kes held the fifth orbital slot and possessed no natural moons. Its climate was intensely frigid, and its surface was composed of frozen rock. This planet, along with its entire star system, was positioned along the Perlemian Trade Route hyperlane. In the Inner Rim, this hyperlane delineated the boundary separating the Northern Dependencies and the Slice.
The planet Kes appeared in "Triplet Threat," a roleplaying game scenario penned by Jason Fry. This adventure was designed for use with Star Wars Roleplaying Game from Wizards of the Coast. It initially appeared on their website on January 22, 2004. Later, in 2009, The Essential Atlas, a reference volume, pinpointed the Tirahnn system, and thus Kes, within grid coordinates N-8.
